to work with.

A hot-wire arrangement is best, but the rig you'd have to make would be
rather large, and with full sheets, a wide table and preferably, with
rollers.

Otherwise, try cutting with one of those fery fine small panel saws,
using a coolant/lubricant. Some plastics (acrylic, for one) should be
cut using water, and paraffin works for others.
